Beskrivelse
Inclusion Criteria:
- Patients who have been diagnosed with chronic hepatitis B (in accordance with the diagnostic criteria of the "Chronic Hepatitis B Prevention and Treatment Guidelines (2022 Edition)") and are currently receiving NAs antiviral treatment for ≥ 6 months or have not received treatment and are ≥ 18 years old;
- Remaining samples (serum) that have undergone combas HBV DNA testing and have clear test results, with the sample collection time frozen for ≤ 6 months;
- The remaining sample volume is sufficient (≥ 1.0 mL), sufficient for digital PCR testing and necessary duplicate testing;
- Samples from the same patient at different time points can be included as independent samples, but the sampling interval time needs to be recorded.
Exclusion Criteria:
- Combine other liver virus infections such as HCV, HDV or HIV;
- Poor sample quality, such as severe hemolysis, lipemia or repeated freezing and thawing ≥ 3 times;
- The samples were not properly frozen and stored (-80℃) after collection or the temperature records were missing;
- The clinical information is severely lacking, making it impossible to confirm the diagnosis and treatment status;
- The duplicate samples already included at the same time point (only the first included sample is retained).

High-concentration group
After detection using digital PCR technology, the results were classified according to concentration levels as follows: high concentration group (≥ 1000 IU/mL); medium concentration group (100 - 1000 IU/mL); low concentration group (20 - 100 IU/mL); extremely low concentration group (below 20 IU/mL); undetectable group.
